in which a piece, square in cross-section, is asreduction proceeds changed in cross-section toa' diamond and square alternately, "the final reduction pass being square.

, arrangementof passes in the respective pairs j 6. "Passes a and Z) are diamond shaped while ofrolls, suitable for such method of rolling is diagrammatically shown in Fig. 5 and Fig.

passesc, e, f, and g are alternately square and diamond, As the rolls 1 feeds onto the delivery table B and as the finished articles should be square in cross-section, the last pass 9 in the rolls 1 should be square as shown in Fig. 5 and as there must be an uneven number of passes to ensure the feeding for the last pass onto the delivery table, and this pass is square, it follows that two succeeding passes, as for example a and b will he the same shape, i. e.', diamond.

In the operation of the mill, the pieces are placed in successio on thereceiving table A, and a piece ted to pass a, the piece moves over therolls 2 onto the rollers of table B. The pieceqis now turned on its axis but not moved laterally and the mill shifted to bring rolls 2 to operative position, said op erations being preferably simultaneous, as will be hereinafter described.

The feed rollers of both tables being reversed, the piece is fed to pass I) in rolls 2, which as before. stated, is diamond shape and moves over rolls 1 into the first groove in therollers of table A. This piece is now turned axially and shifted laterally into the mill shifted and the articles fed through alin'ement with the pass 0., which is a square, and Jhe mill shifted to bringrolls 1 into operative position. A second piece being placed in the first grooves in the rollers of table A, "the rollers of both tables are rotated to feed the pieces to rolls 1 from which they pass onto table B. Both pieces are now turned on their axes but not moved laterally,

the diamond passes b and (Z in rolls 2. These operations are repeated, new piece being placed in position on table A, as previous pieces are shifted laterally. As the last shaping pass is in rolls-1 as hereinbefore described, a finished piece will be delivered, if the mill is full, on each operation of the rolls 1.

lVhile the invention in its broadest aspect are so moved as to push the pieces laterally up the side of the groove and the lateral ,movement is continued causing the piece to move across the ridges intermediate adjacent grooves. As the pieces move across the ridges, the preponderating weight of the portions which have passed beyond the ridges combined with the upward pressure of the fingers against the opposite edges of the pieces will cause an axial turning of the pieces and their dropping into the adjacent grooves. The grooves are so shaped that the pieces will. be held in proper position to enter the square passes in rolls 1. The desired upward and lateral movements 01': the portions of the lingers in contact with the pieces being shifted can be effected preferably by making the fingers portions of levers 28, pivotally mounted in frames 29, secured to the sides of the frames of the feed tables. These levers have their lower ends connected by pitmen 30 to arms 31 on a shaft 32, which is rotated by shaft 8 through iutermeshing bevel pinions 33 as shown in Figs. 1 and 7, so that the, shifting and turning oi the pieces on table A is effected simultaneously with the movement of the mill whereby the rolls 1 are brought to operative )ositions.

In Figs. 11 to 1d inc usive. is shown mechanism adapted. to turn the pieces around their axes, but without changing their positions horizontally. A slotted frame 34; is arranged transverse of the teed table B, being supported by the sides of said table. The side bars of the frames 34 are slotted as at for the reception of the ends of pins 86, on which are pivotally mounted slotted arms 37. These pins are connected together and to a pin 38, passing through a slotted hanger 39 by a bar 10, the pin 38 projecting into the slots 35 in the side bars of the frame 34. The hanger is pivotally suspended from a pin -11, the ends of which )roject into vertical slots 42 in the standard. or post 43 on the frame 34. A bar 4:1: is COHI'IOCtQd by a pi to the hanger at a point intermcdithe mill is being 'hifted to bring the rolls El into operative positiom Nornmlly,v the arms are in such an angular position that the faces of the plates or seats will be nearly parallel with sides of the pieces to be turned, as shown in F 1g.

right and also their vertical movement thepieces are raised high enough in the grooves in the feed rollers to permit of their rotation. When the arms are in mid position 01" vertical position, the vertical movement ceases. its the movement of the arms to the right continues, there will be a further turning on a gradual lowering of the pieces into the same grooves of the rollers. lit will he observed that in the above described operation, the seats 4L7 are shifted from one side of the respective grooves in the rollers and in such shifting are turned through an arc of ninety degrees. After the pieces on table B have been turned, the feed rollers are operated to feed the pieces to reducing rolls, so that the movement of the turning devices to normal position will not be interfered with. This restoration of the manipulating devices of one table to norn'ial position is Gl'fGCtQCl while those oi the other table are being operated to effect the desired change oil position. oi? the: pieces on the other table.
